This article presents a critical–propositional analysis of Chapter 6: Gravity as Orthogonal Tension. The 4D Dimension, Plasmoids, and Nonlinear Continuum Dynamics, associated with the conceptual framework of Topological 0-Matrix/Substrate Mechanics (TSM), in dialogue with the Theory of Objectivity (TO). The study examines the TSM proposal that gravity should not be understood as the curvature of non-material spacetime, but rather as an actual orthogonal tension of an elastic three-dimensional substrate or 3-brane deflected toward a fourth spatial dimension. The analysis evaluates the conceptual structure of TSM in relation to the modal axioms of TO, especially the spherical logical Nothing, uniqueness, infinity as non-element, boundary, triadic observation, recursive composition, and the transcendent element understood as the knowledge or information produced in atomic relations and equivalent to atomic radiations. Particular attention is given to the replacement of black holes by finite topological plasmoids, the rejection of physical singularities, the interpretation of gravitational waves as stress waves, the critique of dark matter and dark energy, and the hypothesis of cosmological redshift as distance-dependent wave dispersion in a viscoelastic substrate. The article argues that TSM offers a fertile mechanical language for TO, especially in the interpretation of gravitational convergence, nonlinear compression, boundary formation, structural jamming, plasmoid dynamics, and the alternation between Reductive and Expansive Inducer Effects. At the same time, the study identifies relevant points of tension: the 0-Matrix appears as a postulated physical substrate rather than as a modally deduced structure; the fourth spatial dimension requires ontological justification; and the replacement of General Relativity and standard cosmology would require robust empirical and quantitative testing. The conclusion assigns the analyzed article a high dialogical relevance to TO, while emphasizing that its strongest contribution lies not in empirical confirmation, but in its capacity to provide an alternative grammar for thinking gravity, tension, non-singularity, radiation, information, and cosmological structure under the modal discipline of the Theory of Objectivity.
